Solar Calculator

Off-Grid Energy System Size Calculator

1. How much electricity do you use each month? Look at your electric bills from the past 6 months (or less) and find the average number of Kilowatt Hours (KwH) per month. Put this number in the space to the right.

KwH/Month

2. What percentage of your house/business power do you want to generate with solar power? If you want to produce 100% of your electricity, put 100.

%

3. How many Peak Sun Hours do you get per day? Look at the Solar Map below to find this number.

Hours

Minimum System Size:

Watts

Divide the Minimum System Size watts by the wattage of the solar panel you are looking at. For example, it would take 24 Mitsubishi 125-watt solar panels to produce 3000 watts..... 3000 divided by 130 = 23+ solar panels. Using our solar calculator will provide you with the exact wattage you need. Have it handy when you come to see us so we can assist in setting up the perfect system for your specific needs.

The hourly figure indicates the average (over the course of the year) amount of insolation (full sun hours) for these zones. These figures are based on the yearly average; consequently, systems based on these figures will provide more power in summer and less in winter. Winter figures for daily solar gain may be from 25% to 50% LESS than these average figures.
